PC gamers have been loyal to you and youll **** this game up if you do xbox360 beta only
reasons:
1: i dont trust 14 year old boys to do proper testing and reporting(no im not a fanboy but the average age on xbox is just lower en tehy only know how to play, nothing of the underlying system, PC gamers do)
2: CE3 is a complicated engine, as a result well probably see bugs with graphics, for crytek its impossible to test on the unlimited configurations possible, so a PC beta could deliver data on both gameplay and the technique behind it(glitches visual bus etc)
if there isnt a PC beta i predict a game riddled with bugs on PC version)
BTW: care to tell us how much MS payed you??
